Beijing is consulting on tighter controls covering 12 photovoltaic manufacturing technologies, threatening to complicate India’s drive to build a domestic solar supply chain.
China has moved to tighten oversight of a group of solar manufacturing technologies, a step that could ripple through an industry already shaped by Beijing’s dominance in equipment, materials and process know-how. According to reports on the proposal, the Ministry of Commerce is considering export controls on 12 technologies linked to photovoltaic production, including processes used for thin silicon wafers, perovskite cells and certain advanced cell architectures. The policy would not amount to a blanket ban on solar exports, but it would make the transfer of specified manufacturing know-how more difficult.
The proposal comes at a sensitive moment for India, where solar companies are trying to deepen domestic manufacturing and cut reliance on Chinese suppliers for critical technology. TradeBrains reported that shares of Waaree Energies, Vikram Solar and Emmvee Photovoltaic Power were weaker after the news, reflecting investor concern that access to advanced production methods could become more constrained. Reuters has previously reported that Chinese restrictions on solar manufacturing technology have already complicated India’s efforts to build a stronger local supply chain.
The draft measures appear to distinguish between outright prohibitions and tighter controls. Reports on the proposal say technologies associated with TOPCon, HJT and XBC cells would face restrictions rather than a total export ban, while other areas, including thin-wafer production, perovskite and tandem cells, and fluidised bed polysilicon processes, could be subject to more severe limits. These are not minor details: each of the technologies sits near the higher end of the solar manufacturing chain and can affect efficiency, cost and scale.
China’s Ministry of Commerce has opened public consultation on the plan until November 15. Until the export-control catalogue is formally amended, companies transferring the listed technologies abroad are required to register certain transactions, according to reports on the draft. The immediate effect is therefore procedural rather than absolute, but the broader signal is clear: Beijing is prepared to treat solar know-how as strategically sensitive, and that could leave overseas manufacturers with less access to the technologies they need most.
